[1/1 Formula]
Work: Calculate the value of equation -√3/3*(-√7+√3+1)*(-√7+√3+1)-2*√3/3*(√3-√7+1)+3 .
Question type: Mathematical calculation
Solution:
-√3/3*(-√7+√3+1)*(-√7+√3+1)-2*√3/3*(√3-√7+1)+3
=-√3/3*0.0863*(-√7+√3+1)-2*√3/3*(√3-√7+1)+3
=-√3/3*0.0863*0.0863-2*√3/3*(√3-√7+1)+3
=-√3/3*0.0863*0.0863-2*√3/3*0.0863+3
=-1.732051/3*0.0863*0.0863-2*√3/3*0.0863+3
=-1.732051/3*0.0863*0.0863-2*1.732051/3*0.0863+3
=-0.57735*0.0863*0.0863-2*1.732051/3*0.0863+3
=(-0.049825)*0.0863-2*1.732051/3*0.0863+3
=(-0.0043)-2*1.732051/3*0.0863+3
=-0.0043-3.464102/3*0.0863+3
=-0.0043-1.154701*0.0863+3
=-0.0043-0.099651+3
=-0.103951+3
=2.896049
Answer:-√3/3*(-√7+√3+1)*(-√7+√3+1)-2*√3/3*(√3-√7+1)+3=2.896049
